Natural Gelflex moulding compound.

Gelflex is a remeltable PVC moulding compound that forms a flexible mould. It has good tensile strength and is very flexible, allowing castings with deep undercuts, ideal for castings made from plaster and concrete.


  • Pack size: 1kg
  • Semi-flexible grade.
  • Melts at 130°C / 135°C and is poured over suitable masters.
  • A release agent is not normally required.
  • Pot life: 3-4 mins
  • Demould: 10 mins
  • Shore hardness: 8A
  • Information sheet (1.5Mb PDF).


A major advantage is that when the mould is worn or requires replacement, it can be cut up, remelted and reused.
